# NSZoneFree

Deallocates a block of memory in the specified zone.

## Declaration

```occ
extern void NSZoneFree(NSZone *zone, void *ptr);
```

## Discussion

Discussion Returns memory to the zone from which it was allocated. The standard C function free does the same, but spends time finding which zone the memory belongs to.
